# operator==(ranges::join_view::iterator, ranges::join_view::iterator)

< cpp‎ | ranges‎ | join view‎ | iterator

friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y ) requires /*ref-is-glvalue*/ && std::equality_comparable<ranges::iterator_t<Base>> && std::equality_comparable<ranges::iterator_t<ranges::range_reference_t<Base>>>; |  | (since C++20)

Compares the underlying iterators.

Equivalent to: return (x.outer_ == y.outer_) and (x.inner_ == y.inner_);, where `outer_` and `inner_` are the underlying iterators. The constant /*ref-is-glvalue*/ in the requires-clause is equal to std::is_reference_v<ranges::range_reference_t<Base>>.

The `!=` operator is synthesized from `operator==`.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `std::ranges::join_view::iterator<Const>` is an associated class of the arguments.

### Parameters
